MUSIC-LEAF TURNER.

SPECIFICATION forming part of Letters Patent No. 414,870, dated November12, 1889.

Application filed September 7,1888. Serial No. 284,822. (No model.)

ing drawings, and to the letters of reference marked thereon` which formpart of this specification.

My invention relates to appliances for turning the leaves of printed orWritten musicscores; and the object of my invention is to provide asimple and inexpensive music-leaf turner, which shall be -reliable inaction, and which may be operated by a quick and easy movement of theplayers hand, so that no interruption shall occur in the time in whichthe composition is to be played.

To the above purposes my invention consists in .certain peculiar andnovel features of construction and in certain combinations of parts,as-hereinafter described, and pointed out'in the claims.

In order that my invention may be fully understood, I will proceed todescribe it with reference to the accompanying drawings, in which-Figure lis a front elevation of a musicleaf turner constructed inaccordance with my invention. Fig. 2 is a vertical longitudinal sectionof the devices for operating the leaf-turning arms on line x a: of Fig.l. Fig. 3 is a front view of the same. A

In the said drawings, A designates the frame or backing of the device,said frame being of oblong rectangular shape and provided with suitablecross pieces B, which serve to strengthen the frame, and also as themeans for receiving suitable connect-ions for attaching the device tothe music-rack of a piano, organ, music-stand, or other similarstnucture. The lower side of the frame A is provided with a shelf C,which supports the music-score in proper position upon the frame of thedevice, and D designates a rod or bar the lower end of which is rivetedor otherwise secured to the middle of shelf B, and which extendsvertically upward therefrom. This rod is designed to lie upon the creaseor fold of the score, and thus retain it in proper position while theleaves are being turned, as hereinafter described. The left-handcrosspiece B is extended downward below the shelf C, and forms a bracketE, the lower end of which is turned outward at right angles to the mainportion, as shown at F. The outer end of this arm Fis bent upward atright angles, as shown at G, and the outer portion of t-he part G isgrooved longitudinally for a purpose to be presently explained.

II designates a shaft, the lower end of which is connected to the aim Fof bracketE about midway of the length of said arm, and the upper end ofwhich is riveted or otherwise suitably secured to the adjacent portionof shelf C. Upon the upper part of shaft H is secured a U-shaped frameI, the outer ends of the arm's of which are formed with heads J Jthrough which the shaftH passes loosely.

K designates the arms or iingers by means of which the leaves of thescore are turned. Each of these arms is of L shape, one portionextending horizontally beneath ledge C and the other portion extendingvertically, so as to lie between the leaves of the score. Each of thesearms is connected at the extremity of its horizontal portion with a hubL, which isloosely centered upon the shaft H, before referred to. Theperiphery of each of these hubs L is grooved for a portion of itsextent, and from thence is formed with a V- shaped cani M. These hubs,of which there may he any desired number (three being shown) tocorrespond with the number of arms or iingers K, are confined betweenthe heads J of frame I, before referred to.

N designates three spiral springs, each of which is attached at one endto the periphery of one of the hubs L just beyond the point of the camM, and the opposite ends of which are attached to the extended end O ofthe right-hand cross-piece B, as shown, the peculiar forni and purposeof said extension O being hereinafter more fully explained.

P designates an arm which extends horizontally outward from the lowerpart of bracket-arm E, and upon the outer end of IOO this arm P ispivoted an operating-lever R, which extends laterallydownward, so as tolie conveniently near to the key-board of the instrument, as indicatedin Fig. l. Midway of the length of that part of level-,R which liesacross the bracket Eis placed a pin S, which passes through a bolt orcatch T, the latter lying in the concave groove of .arm G, beforereferred to, and said pin S also works through a slot U in the upturnedarm G, as shown in Fig. 2. A spiral spring V surrounds the bolt T andarm G and serves to hold the bolt normally thrown upward, so as toengage with the ends of the cams M on hubs L. The sides of the hubs Lare preferably hollowed out, as shown in Fig. 2, so as to reduce thefriction of t-he parts of said hubs which lie in contact with eachother.

At the lower left-hand corner of the frame A is formed a hooked-shapedextension WV, which carries a rubber or other elastic cushion or bufferIV'. as shown. At the lower end of the right-hand cross-pieces B isformed the extension O, before referred to. The lower end of thisextension is bent outward and upward upon itself, so as to form a hookO', said parts being for purposes to be hereinafter explained.

Upon the right-hand end of frame A is placed a T-shaped bar X. The endsof the cross-piece are journaled in bearings X. For a portion of itslength one arm of the cross-piece is surrounded by a coiled spring X2,which tends to hold the arm of the bar down in'the position shown inFig. l. A pin X3 is formed upon the opposite end of the cross-piece ofbar :r in position to engage with the shoulder on the upper bearing whenthe bar is raised, and thus hold said bar in its raised position whendesired.

The operation of the described mechanism is as follows: The music sheetor score is placed with its crease beneath the barD, and the .verticalends of the arms or fingers K are inserted beneath the leaves, said armsor iingers lying over tothe right, and the outer end of the bolt orcatch T lying across the ends of cams M. This engagement of cams M andcatch T is effected by sliding the frame I downward upon the shaft II,and such movement of the frame causes the upper end of arm G to engagewith the ends of cams M of the two lower hubs L, thus partiallyrelieving catch T of the strain produced by the tension of springs N.The catch Tis further relieved of such strains by means of the hook O atthe lower end of the right-hand crosspiece B, said hook catehin over thetwo lower arms of finger K. Now when the performer desiresA to turn aleaf he simply delivers a quick stroke upon the lower end of lever R,which depresses bolt or catch T sufficiently to release the cam of theupper hub L. The tension of the corresponding spring N .rotates the hubL toward the left, causing the corresponding arm or finger to ilyquickly to the left, carrying the leaf with it. Aty the same time thelower face of the cam M rides upon the upper end of arm G and carriesframe I upward a sufficient distance to bring` thenext lower hub intoposition to be tripped by a subsequent depression of the lever R. As thearms fly over to the left they strike the buffer l I', which gentlyarrests their movement and renders their action noiseless. It is to beobserved that in case of a repeat in the score the leaf may be readilyturned back by hand to the point of beginning of the repeat, owing tothe fact that the operative devices are set'cccentric to the crease ofthe score, thus allowing the arms K to leave the sheet when they reachthe limit of their movement to the left. Thus it will be seen that Ihave produced a music-leaf turner which is simple and inexpensive inconstruction, and which is quick and reliable in operation, and also bymeans of which the leaves may be readily turned by the performer wit-l1-out producing anyinterruption of the time in which the composition is tobe performed.

It is evident that various modifications in mere details of constructionmay be adopted without departing from the spirit of my invention, andhence I refer to the ensuing claims as specifying the nature of thesame.

Having thus described my invention, what I claim as new therein, anddesire to secure by Letters Patent, is-

l. In a music-leaf turner, one or more spring-actuated hubs havingcam-surfaces upon their peripheries and carrying the leafturning finger,in combination with a springpressed catch or bolt for holding andreleasing said hubs and serving to guide the latter successively intooperative position, and a lever for throwing said bolt to release thehubs, said leverextending into convenient position to be depressed bythe performer, substantially as described.

2. In a music-leaf turner, a bracket located at the lower part of theframe and provided with an axle and with an arm at its'outer part, incombination with one or more hubs carrying the leaf-turning arms andprovided with cams upon their peripheries, a springpressed bolt or catchworking upon the bracket-arm, a lever fulcrumed upon the bracketframeand operatively connected to the catch, so as to retract the same. intoposition to successively release the hubs and carry them into operativeposition, substantially as set forth.

3. The combination of a series of springactuated hubs for carrying theleaf-turning arms mounted in a bracket-frame secured to the main frame,and an arm arranged to engage and hold the lower hub in readiness to bemoved into operative position, substantially as described.

4E. The combination, with a series of springactuated leafturning armspivotally connected to the main frame, of a hook-shaped projection fromthe main frame extending in parallel relation with the axis of thespring- IOO IIC

actuated hubs arranged to hold one of said arms in readiness to be movedinto operative position, substantially as described.

5. In a music-leaf turner, an arm or projection secured to the mainframe and provided with a buffer or cushion to limit the movements ofthe leaf-turning arms when thrown to turn a leaf, substantially asdescribed.

6. In a music-leaf turner, a T-shaped springpressed holdin g-bar mountedin bearings upon one side of the main' frame, in combination with a pinupon the bar adapted to engage with the shoulder to hold the free end ofthe bar in raised position, substantiallyas speciied.

In testimony that I claim the foregoing` as my own I hereby aix mysignature in presence of two Witnesses.

JACOB REISINGER.
